I have a big band chart with 17 instruments.  When I edit each parts (Document/Edit Parts), each part appears as I would expect.  Except the guitar part.  In page view, all that shows up is the title, the instrument name, composer name and the copyright symbol at the bottom, but no staves, no music - just a blank page.  If I go to scrollview, all the measures and notes are there.  I tried printing the part out, and oddly, it prints out and at first looks fine, but I have an 8-bar section that repeats and the printed version shows only one bar between the repeats.  I'm aware that this or similar issues have been discussed but I couldn't find anything that was right on point.
